Title: Dual mode sheet feeder
Inventor: PETOCCHI ERMANNO C
IPC: B65H1/04
Filed: 1995-08-11
Abstract: An apparatus which advances sheets from different stacks of sheets. In one mode of operation, two stacks of sheets are supported side by side. A sheet feeder associated with each stack of sheets advances successive uppermost sheets from the respective stack to a transfer station of a printing machine. Alternatively, a single sheet feeder mounted movably in the sheet feeding apparatus may be employed to advance successive sheets from each of the stack of sheets, in lieu two sheet feeders. In the absence of these stacks of sheets, another oversized stack of sheets may be positioned in the sheet feeder. This oversized stack of sheets extends from a first sheet storing section into a second sheet storing section. When two stacks of sheets are disposed in the sheet feeder, one stack is positioned in the first sheet storing section and the other stack is positioned in the second sheet storing section. In this way, the sheet feeding apparatus has capability of feeding multiple size sheets.

Title: Segmented Adjustment Riser
Inventor: BAVINGTON GREGORY F
IPC: E02D29/12
Filed: 1995-09-22
Abstract: A segmented adjustment riser for maintenance holes is formed from a set of similar elongated one-piece segments.  Each segment has two opposite ends provided with respective interengaging formations, and the segments are placed together end to end to form an endless riser member having planar upper and lower sides. The formations interengage and resist lateral displacement of each end of each segment relative to the adjacent end of each adjacent segment.  The segments can be manufactured relatively easily and with greater economy than the corresponding one-piece riser member and facilitate handling and installation.

Title: Method and apparatus for sewage treatment
Inventor: STROHMEIER ANDREAS
IPC: C02F3/06
Filed: 1995-09-25
Abstract: A method is disclosed for sewage treatment, in particular for municipal sewage. The method has a mechanical purification stage (11, 40), a first biological purification stage (12, 41) and a second biological purification stage (13, 42). The second biological purification stage (13, 42) is a biological filter system, which has a filter stage for nitrification (20, 47) and a filter stage for denitrification (21, 48) connected downstream of the first mentioned stage. The filter stages have at least one biological filter (70). According to the invention, in the first biological purification stage (12, 41), the carbon load and in addition at most the nitrogen load occurring on a 24-hour average (nitrogen impact coefficient fN = 1. 0) at the measurement temperature is reduced. In the second biological purification stage (13, 42), the nitrogen loads that exceed this, an in particular the daily peaks (fN > 1.0), are reduced to a predeterminable extent, even at low temperatures (< 12°C). A sewage treatment plant for carrying out the method is also disclosed and claimed.

Inventor: DAVID JERRY J
IPC: F16H57/02
Filed: 1995-11-03
Abstract: The new drive arrangement involves a machine having upper and lower decks with respective upper and lower openings through them.  The drive arrangement includes a flanged bearing housing attached to the lower deck.  The upper opening and the bearing housing are configured to permit the bearing housing to pass through the upper opening.  The flange is attached to the upper surface of the lower deck member and so configured and arranged, the drive arrangement may be installed through the upper opening.  The new drive arrangement may be fully assembled with bearing, bearing housing, grease trap and pinion gear for mounting "top down" onto the deck members, thereby eliminating the need for bottom access and greatly simplifying initial installation and later repair.  A new method for mounting a drive arrangement is also disclosed.

Title: A baton projectile
Inventor: SAXBY MICHAEL ERNEST
IPC: F42B12/74
Filed: 1994-06-27
Abstract: A baton projectile comprises a case (1) of low density polyethylene and a core (2) of a soft material such as a thermoplastic gel modified rubber. An air gap (4) is optionally formed at the front end of the baton projectile between the core (2) and the case (1). Upon impact with a target at acceptable forces the air pocket (4) reduces the speed of sound of the impact shockwave to reduce the risk of unacceptable bone injury to the target. At higher than acceptable impact forces, the case (1) ruptures and the core (2) spreads out to radially disperse the excess impact energy and to present a larger impact area to the target so that the risk of unacceptable penetration and trauma injury to the target is reduced.

Abstract: A heat exchanger for exchanging heat between first and second fluids.  A plurality of vertically oriented passages are defined between alternating first and second passage walls. The first and second passages are provided for bringing the first and second fluids into a heat transfer relationship. To this end, the first passage incorporates an inlet and an outlet, for instance, to admit gaseous nitrogen into the top of the first passages and to discharge condensed nitrogen from the bottom of the first passages. An inlet is provided to introduce the second fluid into the second passages. The second fluid, which is a liquid is to be at least in part vaporized within the second passages. Liquid film, composed of the liquid, is distributed within the second passages by way of an arrangement of slotted dividing bars having staggered slots along the length of such slotted dividing bars to urge liquid against the passage walls defining the passages. Additionally, or in place of the dividing bar arrangement, a multi-domain corrugated fin material arrangement can be provided to effect a liquid film distribution within the second passages.
